Examining ray and skate diversity in the Irish Sea using DNA barcodes: Research project data

All of the supplementary material to accompany the 4th year research project 'Examining ray and skate diversity in the Irish Sea using DNA barcodes'. Data includes <em>Cytochrome c oxidase I</em> (COI) sequences generated in this project from <em>Raja </em>specimens, agarose gel electrophoresis images of DNA samples, DNA concentrations of DNA extractions from <em>Raja </em>specimens as well the accession numbers of sequences sourced from GenBank that were used to construct a maximum likelihood tree.
